A further object of the invention is to provide a universal finishremover which has no obnoxious odors.

A finish remover made in accordance with the present invention comprisesa combination of volatile solvents and a gelatinizer which is dissolvedby one of the solvents and serves to form a film which will retard theevaporation of the solvents.
